Descriptions: 1.Please feed corresponding DC voltage to DC voltage termination £¬ wrong or reverse power will damage it; 2. Please set up product function firstly£¬ use FS button to select 1-18 functions; 3. After selecting the function£¬ double-click the FS button will display 't'£¬ then adjust the time £¬ using "8 Sel' button and "0-9 Sel' two buttons to adjust the time £¬ "8 Sel" button to select which characters to adjust £¬ "0-9 Sel" adjust the value ; 4. For double- time adjustment£¬ after selecting the function£¬ and then double-click the FS button £¬it will appears t1£¬double -click the FS button£¬it will appears t2£¬ use 8 Sel 0-9 Sel two buttons to adjust time£¬ then double-click again£¬it will need to set the "n" for cycle number; 5. Seconds delay time 1-999 seconds and 1-999 minutes can be select by long press FS button£¬it will show A representative of the range is 1-999 seconds £¬b for 1-999 minutes; 6. Function 17 and 18 do not need to adjust the time £¬for these two function £¬ the trigger signal to trigger interface can direct control relay; 7. Trigger selection: When the middle pin is connect to the L -side (jumper) £¬it is low level trigger £¬ a switch between IN terminal and DC- termination can also be used for triggering £¬ the jumper is connected to the middle and H £¬ It is the high level trigger£¬ a switch between IN terminal and DC+ termination can also be used for triggering;
